ABSTRACT:
The apparatus for washing or drying vehicles has a conveyor belt drawing the vehicle through the apparatus and a flexible support member (4), guided in a horizontal plane above the plane of movement of the vehicle over a plurality of return wheels (5, 6), with a multiplicity of narrow strips (10) of absorbent material connected with said support member and vertically suspended therefrom. Two strands (4, 4b) of the support member (4) extend at an angle (.alpha.) obliquely relative to the direction (B) of movement of the vehicle. The strand (4a) facing the front end of the vehicle is driven in a direction which has a velocity component (K1) oriented opposite to the direction (B) of the vehicle advance. That strand (4b) of the support member (4) which faces toward the tail (1b) of the vehicle is inclined at such an angle (.alpha.) relative to the direction (B) of vehicle advance that its motion has a velocity component (K2) which is oriented in the direction (B) of the vehicle advance. This angle (.alpha.) and the velocity (G) of the support member (4) are so selected, that the velocity component (K2), oriented in the direction (B) of vehicle advance, of the strand (4b) facing the tail (1b) of the vehicle, is greater than the speed (V) of the conveyor belt.
